Title: Die cast product formed with aluminum plating
Inventor: KOURA SETSUKO
IPC: C25D5/24
Filed: 1991-10-30
Abstract: PURPOSE:To obtain the die cast product which can form a colored layer having stable color tones without being affected by material quality and surface layer. CONSTITUTION:Aluminum, magnesium, zinc or the alloy thereof is die cast to form a base body having a prescribed shape. The aluminum layer is formed on the entire surface on a part thereof on the surface of the base body by an electrical plating method. The electric aluminum plating layer constitutes a substrate for coloration after being subjected to an anodic treatment. Coating, electrolytic coloring, etc., are adopted for the coloration. The electric aluminum plating layer negate the material quality of the base body and the state, etc., of the surface layer and forms the consistent surface layer. Consequently, the colored layer formed thereon has eventually the stable color tones regardless of the material quality of the base body and the state, etc., of the surface layer.

IPC: G05D16/06
Filed: 1992-11-24
Abstract: PURPOSE:To provide the automatic pressure control valve which can provide sufficient pressure at a valve element and improves manufacture efficiency even when second-order side pressure reaches prescribed pressure. CONSTITUTION:A non-bleed type automatic pressure control valve 20 is formed by providing a pressure diaphragm 222 for moving a valve element 212 in the closing direction while being engaged with the valve element 212 and receiving the second-order side pressure and a diaphragm motor 230 for energizing the valve element 212 in the opening direction.

Title: Cylinder for hydro-pneumatic suspension
Inventor: HAYASHI KENJI
IPC: F16F9/32
Filed: 1993-11-19
Abstract: PURPOSE:To improve durability of a diaphragm and prevent occurrence of gas permeability in a gas chamber by providing the diaphragm composed of laminated resin films of gas impermeability and forming a volumetric fluctuation part whose shape or position is varied. CONSTITUTION:A diaphragm 53 is composed of a resin laminated film having gas-impermeable property, and engaged with a flange of an insertion member 12 arranged in an outer cylinder 1 and an upper end of a plug 25 in an air-tight manner. It is divided into a gas chamber 51 in which external N gas is charged and a liquid chamber 52 which is communicated with an operation chamber 21 through an oil passage 24. A bent portion 54 formed in a form of pleats is extended circumferentially and formed cylindrically. When the pressure in the operation chamber 21 is high, the pressure of oil in the liquid chamber 52 is also high. Thus, the diaphragm 53 is inverted in the outward direction of the diameter, and volume fluctuation in a high pressure chamber 5 is enabled without extending and contracting the diapragm 53 itself. Durability of the diaphragm 53 is thus improved.
